Description

Technical Field

[0001] This invention relates to the technical field of machining, and particularly to punching assemblies and profile processing lines. Background Technology

[0002] The processing of profiles is generally divided into feeding, cutting, punching and unloading. In order to improve the processing efficiency of profiles, conveyor belts can be used to connect the various processing equipment in the processing sequence to realize production line production.

[0003] After being cut, the profile is formed into multiple square tubes. Existing automated punching equipment generally only punches the wide side of the square tubes. For example, the existing technology, "Punching Assembly and Profile Processing Line Including Thereof" with publication number CN219786229U, can automatically punch the wide side of multiple square tubes at the same time. However, for punching the narrow side of the square tubes, it is easy to tip over during transportation due to insufficient stability. Therefore, punching can only be done manually by setting the die, which results in extremely low processing efficiency.

[0004] In addition, since the automated punching equipment is one link in the production line, if the narrow side of the square tube is to be used as the bottom, the upstream cutting equipment and feeding equipment need to be adjusted. However, with the current level of technology, it is not possible to support the profile to be fed vertically, and it will inevitably tip over during feeding. Summary of the Invention

[0005] The present invention aims to provide a punching assembly to solve one or more technical problems existing in the prior art, and at least provide a beneficial alternative or creation condition.

[0006] A punching assembly according to a first aspect embodiment of the present invention comprises:

[0007] A frame, to which the first conveyor line is connected;

[0008] The system includes two motion modules, located on opposite sides of the first conveyor line and movably connected to the frame. The movement direction of each motion module is orthogonal to the conveying direction of the first conveyor line. Each motion module is connected to a lower die, which has vertical die cores facing each other. Each vertical die core has a first outer end face facing the opposite vertical die core, and all first outer end faces are connected to a material hanging part. At least one motion module has a first die hole in the vertical die core, and a stamping mechanism is provided at the corresponding position of the first die hole.

[0009] The lifting mechanism has a lifting part that moves up and down. The moving path of the lifting part passes through the conveying surface of the first conveying line, and the position of the lifting part corresponds to the position of the vertical mold core.

[0010] The punching assembly according to an embodiment of the present invention has at least the following beneficial effects: When punching the narrow side of a square tube is required, the wide side of the square tube is first placed on the first conveyor line as the bottom surface. After the first conveyor line transports the square tube to the designated position, the lifting mechanism lifts the square tube upward through the lifting part. Then, the two motion modules move towards the first conveyor line until the hanging parts on both sides extend into the interior of the square tube. Then, the lifting mechanism controls its lifting part to descend, leaving enough space for the square tube to flip. At this instant, since the square tube loses the support of the lifting part, it is under the influence of gravity... Under the action of the material hanging part, the square tube is flipped from a horizontal state to an vertical state. After that, the two motion modules continue to move towards the first conveyor line until the vertical die cores on both sides extend into the interior of the square tube. At this time, the two ends of the square tube are supported by the two vertical die cores and block the first die hole. Finally, the stamping mechanism drives the upper die to stamp towards the first die hole, thus completing the punching of the narrow side of the square tube. Compared with the prior art, the punching assembly can realize automatic punching of the narrow side of the square tube, effectively improving processing efficiency, and can also prevent the square tube from tipping over during conveying, thus improving the stability of processing.

[0011] According to some embodiments of the present invention, the first conveyor line is connected to a first stop mechanism on its conveying path. The first stop mechanism has a first stop portion that moves up and down, and the lifting mechanism is located upstream of the first stop mechanism. The first stop portion is used to define the relative position of the square tube on the first conveyor line, so that the vertical mold cores located on both sides of the square tube can be precisely inserted into the openings on both sides of the square tube.

[0012] According to some embodiments of the present invention, the vertical mold core is provided with a first guide slope. When the two vertical mold cores gradually extend into the openings on both sides of the square tube, the two ends of the square tube can be positioned and supported outside the two vertical mold cores by the first guide slope, thereby defining the relative position between the square tube and the lower mold.

[0013] According to some embodiments of the present invention, the motion module has a chip removal groove below the lower die, and the projection of the chip removal groove on the horizontal plane covers the projection of the first die hole on the horizontal plane, so that the punched piece can fall from the chip removal groove into the collection container located below.

[0014] According to some embodiments of the present invention, each of the lower dies is provided with a plurality of vertical die cores, and all the vertical die cores of each lower die are equidistantly spaced along the conveying direction of the first conveying line to achieve synchronous punching of multiple square tubes.

[0015] According to some embodiments of the present invention, the motion module has a transverse mold core below or above the vertical mold core, a slot is reserved between the transverse mold core and the vertical mold core, and the transverse mold core has a second mold core corresponding to the first mold core. Before punching, the square tube is lifted by the lifting mechanism to a height corresponding to the vertical mold core or the transverse mold core. With the above configuration, the punching assembly can punch not only the narrow side of the square tube, but also the wide side of the square tube, thus having wider applicability.

[0016] According to some embodiments of the present invention, the transverse mold core is provided with a second guide slope. When the two transverse mold cores gradually extend into the openings on both sides of the square tube, the two ends of the square tube can be positioned and supported outside the two transverse mold cores by the second guide slope, thereby defining the relative position between the square tube and the lower mold.

[0017] According to some embodiments of the present invention, the lower mold is connected to a demolding mechanism, which has a demolding portion extending toward the first conveyor line. After punching is completed, the two motion modules move away from the first conveyor line, at which time the demolding mechanism drives the demolding portion to extend toward the position of the square tube, thereby realizing the demolding of the square tube from the lower mold.

[0018] According to a second aspect embodiment of the present invention, a profile processing line includes a feeding assembly, a cutting assembly, a second conveyor line, and the aforementioned punching assembly. The feeding assembly, the cutting assembly, and the second conveyor line are sequentially connected. The first conveyor line is connected to the side of the second conveyor line. The second conveyor line is provided with a first pushing mechanism, which has a pushing direction parallel to the first conveyor line.

[0019] The profile processing line according to the present invention has at least the following beneficial effects: the profile processing line integrates four processes: feeding, cutting, punching and unloading, thereby realizing the automated processing of square tubes.

[0020] According to some embodiments of the present invention, the second conveyor line is provided with an openable and closable baffle gate, which is located downstream of the first pushing mechanism. If the square tube needs to be punched, the baffle gate is closed, and the first pushing mechanism pushes the square tube requiring punching from the second conveyor line to the first conveyor line; if the square tube does not need to be punched, the baffle gate is opened, and the square tube is fed along the second conveyor line.

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] like Figures 1 to 3 As shown, the punching assembly according to a first aspect embodiment of the present invention includes a frame 100 and two motion modules 200. The frame 100 serves as the mounting reference for all components. Each of the left and right sides of the frame 100 is provided with a first slide rail 110 arranged in a front-rear direction. A first conveyor line 300 is connected to the frame 100, having a right-to-left conveying direction. The conveying end of the first conveyor line 300 is connected to a downwardly inclined unloading plate 330. The first conveyor line 300 can be selected as a conveyor belt of a certain width, or it can be composed of two parallel and spaced-apart conveyor lines 310. In this embodiment, to accommodate square tubes of different lengths, the first conveyor line 300 is preferably composed of two parallel and spaced-apart conveyor lines 310.

[0036] Specifically, each of the conveyor branches 310 is a narrow conveyor belt. One conveyor branch 310 is fixedly connected to the frame 100, while the other conveyor branch 310 is slidably connected to two first slide rails 110 of the frame 100 via an external sliding plate 320, making the spacing between the two conveyor branches 310 adjustable. To adjust the spacing between the two conveyor branches 310, the frame 100 and the fixedly installed conveyor branch 310 are each connected to a lead screw 400 via bearing seats. The sliding plate 320 is provided with a nut block 410 that is threadedly connected to the lead screw 400, and a handwheel 420 is connected to the end of the lead screw 400. When the user rotates the handwheel 420, the lead screw 400 also rotates, thereby moving the nut block 410 along the length of the lead screw 400, ultimately achieving the adjustment of the spacing between the two conveyor branches 310.

[0037] Furthermore, the driving wheels of the two conveying branches 310 are connected to a regular polygonal drive shaft 311 to achieve synchronous connection of the two driving wheels. Since the length of the regular polygonal drive shaft 311 is greater than the maximum adjustment amount between the two conveying branches 310, the regular polygonal drive shaft 311 can ensure synchronous connection of the two driving wheels regardless of how the distance between the two conveying branches 310 is adjusted, so that the two conveying branches 310 can share the same conveying motor 312.

[0038] Furthermore, the two motion modules 200 are respectively located on the front and rear sides of the first conveyor line 300. The slide plate 320 connected to the conveyor branch line 310 has a second slide rail 321 arranged in the front-rear direction on its upper surface. One of the motion modules 200 is slidably connected to the two second slide rails 321 of the slide plate 320, and a first hydraulic cylinder 201 is connected between the motion module 200 and the slide plate 320. The position of the motion module 200 on the slide plate 320 is controlled by the first hydraulic cylinder 201. At the same time, the other motion module 200 is slidably connected to the two first slide rails 110 of the frame 100, and a second hydraulic cylinder 202 is connected between this motion module 200 and the fixedly arranged conveyor branch line 310. The position of the motion module 200 on the frame 100 is controlled by the second hydraulic cylinder 202. In summary, the moving directions of the two motion modules 200 are orthogonal to the conveying direction of the first conveyor line 300. When the user rotates the handwheel 420, the movable conveyor branch line 310 and the corresponding motion module 200 can move simultaneously toward the fixed conveyor branch line 310 to adapt to square tubes of different lengths. After the user adjusts the relative positions of each component according to the size of the square tube, the two motion modules 200 can simultaneously approach or move away from the first conveyor line 300 under the drive of their respective hydraulic cylinders.

[0039] It should be noted that the present invention does not limit the spacing adjustment mechanism of the first conveyor line 300, nor does it limit the two motion modules 200 to be driven by hydraulic cylinders. Those skilled in the art can replace the above embodiments with existing mechanisms, and are not limited to the embodiments disclosed in the present invention.

[0040] like Figure 1 and Figure 4As shown, in order to punch holes in the narrow face of the square tube on the first conveyor line 300, both motion modules 200 are connected to lower dies 210. Each of the two lower dies 210 has multiple vertical die cores 220 facing each other. The vertical die cores 220 are set according to the vertical state of the square tube, that is, the vertical dimension of the vertical die core 220 is larger than its horizontal dimension. All the vertical die cores 220 of each lower die 210 are equidistant from each other in the left-right direction. Each vertical die core 220 has a first outer end face 221 facing the opposite vertical die core 220. Each of the four sides of the first outer end face 221 is chamfered to form a first guide slope 222. Each of the vertical mold cores 220 has a material hanging part 223 connected to its first outer end face 221. The size of the material hanging part 223 is not greater than the size of the vertical mold core 220. The material hanging part 223 is located on the upper part of the vertical mold core 220 and its shape can be a rotating body.

[0041] Next, both motion modules 200 are provided with a first die hole 224 on each vertical die core 220, and both motion modules 200 are connected to a stamping mechanism 500 above each lower die 210. The stamping mechanism 500 can be a hydraulic cylinder, which is provided with a telescopic drive part. The end of the drive part is connected to an upper die 510. The upper die 510 is matched with the first die hole 224 to realize the punching of square tubes.

[0042] Since the square tube is conveyed by the first conveyor line 300, before punching the square tube, it is necessary to limit the position of the square tube on the first conveyor line 300 so that when the two motion modules 200 approach the first conveyor line 300 at the same time, all the vertical die cores 220 located on the front and rear sides can extend into the openings on both sides of the corresponding square tube. For this purpose, both conveyor branches 310 are connected to a first blocking mechanism 600. The first blocking mechanism 600 can be a cylinder. The first blocking mechanism 600 is provided with a first blocking part 610 that can be raised and lowered. Each first blocking part 610 is connected to a first inductive switch 611. The first blocking part 610 can rise above the conveying surface of the first conveyor line 300 or fall below the conveying surface of the first conveyor line 300. When multiple square tubes are placed on the first conveyor line 300 at the same time, if the square tube at the end is blocked by the first stop part 610, the multiple square tubes are arranged side by side in the left and right direction, so that all the vertical mold cores 220 located on the front and rear sides can be accurately inserted into the openings on both sides of the corresponding square tube.

[0043] Finally, to flip the square tube from a horizontal to an vertical position, a lifting mechanism 700 is connected upstream of the first conveyor line 300 to the first stop mechanism 600. Since the first conveyor line 300 is composed of two conveyor branches 310, the number of lifting mechanisms 700 can be selected as two, with each lifting mechanism 700 connected to one of the two conveyor branches 310. The lifting mechanism 700 can be a cylinder, which has a lifting part 710 that can be raised and lowered. Each lifting part 710 has a magnet block 711 connected to its upper surface. The lifting part 710 can rise above the conveying surface of the first conveyor line 300 or descend below the conveying surface of the first conveyor line 300. The position of the lifting part 710 corresponds to the position of the vertical mold core 220, so that the rising path of the square tube intersects with the moving path of the vertical mold core 220. It is understood that the lifting mechanism 700 may also be connected to the lower mold 210 of the motion module 200, and is not limited to the above embodiments.

[0044] Using the above structure, when punching the narrow side of a square tube, the wide side of multiple square tubes is first placed on the first conveyor line 300 as the bottom surface. The first conveyor line 300 conveys the multiple square tubes. At the same time, the first stop mechanism 600 drives the first stop part 610 to rise, thereby limiting the position of the multiple square tubes on the first conveyor line 300. After the first inductive switch 611 on the first stop part 610 is triggered for a period of time, the lifting mechanism 700 drives the lifting part 710 to lift the multiple square tubes upward. In this embodiment, a second inductive switch (not shown in the figure) is set to limit the lifting height of the lifting part 710, so that the square tubes can be aligned with the vertical mold core 220 in terms of height. After this, the two motion modules 200 move towards the first conveyor line 300 under the drive of their respective hydraulic cylinders until the hanging parts 223 on both sides extend into the interior of each square tube. Then, the lifting mechanism 700 controls its lifting part 710 to descend, and the first blocking mechanism 600 controls its first blocking part 610 to descend, so as to reserve enough space for the square tube to flip. At this moment, since the square tube loses the support of the lifting part 710, and since the shape of the hanging part 223 is a rotating body or its position is off-center from the center of the square tube, the square tube can flip around the hanging part 223 under the action of gravity, so as to flip the square tube from a horizontal state to an upright state. Subsequently, the two motion modules 200 continue to move closer to the first conveyor line 300 until the vertical die cores 220 on both sides extend into the interior of each square tube. As the vertical die cores 220 on both sides gradually extend into the openings on both sides of the square tube, the two ends of each square tube can be positioned and supported outside the two vertical die cores 220 by the first guide slope 222 and block the first die hole 224, thereby limiting the relative position between the square tube and the lower die 210. Finally, the stamping mechanism 500 drives the upper die 510 to stamp in the direction of the first die hole 224, thus completing the punching of the narrow side of the square tube. It should be noted that since the upper surface of the lifting part 710 is connected to the magnet block 711, the relative position between the multiple square tubes is temporarily fixed during the process of the lifting part 710 lifting multiple square tubes, so as to avoid the multiple square tubes from deviating in position during the lifting process.

[0045] After punching, the upper die 510 is driven upwards by the stamping mechanism 500, and both motion modules 200 move away from the first conveyor line 300 under the drive of their respective cylinders, allowing the square tube to fall back onto the first conveyor line 300 for unloading. Since the square tube can be unloaded directly after punching, even if it tilts while falling back onto the first conveyor line 300, it will not affect subsequent unloading. In other embodiments, after punching, the lifting mechanism 700 drives its lifting part 710 upwards to replace the square tube, allowing the square tube to descend onto the first conveyor line 300 along with the lifting part 710, thus maintaining the consistency of all square tubes.

[0046] Furthermore, after punching, the square tube may be difficult to demold, causing it to reset along with the motion module 200. To solve this problem, the lower mold 210 is connected to a demolding mechanism 800, which can be a cylinder. The demolding mechanism 800 has multiple demolding parts 810 extending towards the first conveyor line 300. All demolding parts 810 pass through the lower mold 210 and are located below the corresponding vertical mold core 220. After punching, the two motion modules 200 move away from the first conveyor line 300. At this time, the demolding mechanism 800 drives the demolding parts 810 to extend towards the square tube, achieving smooth demolding of the square tube from the lower mold 210 through a push-pull action. It is understood that the present invention does not limit the specific structure of the demolding mechanism 800. As long as the demolding mechanism 800 can demold the square tube, regardless of the structure of the demolding mechanism 800, it is within the protection scope of the present invention.

[0047] In other embodiments, if the square tube is punched on one side, only one of the motion modules 200 needs to be provided with the first die hole 224 and the upper die 510, or only one of the stamping mechanisms 500 needs to be activated. Moreover, the first stop mechanism 600 is not necessary. When the first stop mechanism 600 is not provided, the stroke parameters of the two motion modules 200 need to be strictly matched with the stroke parameters of the first conveyor line 300 so that when the square tube is conveyed to the designated position, all the vertical die cores 220 located on the front and rear sides can extend into the openings on both sides of the corresponding square tube. However, this places high demands on the control of the system, so the above configuration is not a preferred embodiment.

[0048] In some embodiments of the present invention, the motion module 200 has a chip removal groove 240 below the lower die 210. The projection of the chip removal groove 240 on the horizontal plane covers the projection of the first die hole 224 on the horizontal plane, so that the punched piece can fall from the chip removal groove 240 into the collection container of the frame 100.

[0049] The above-described structure is an embodiment of the present invention, which is mainly used for punching the narrow side of a square tube. However, the present invention also provides an embodiment two, in which the punching assembly 10 can punch not only the narrow side of the square tube, but also the wide side of the square tube.

[0050] like Figure 5 As shown, this is a three-dimensional structural diagram of the lower mold 210 in Embodiment 2. Unlike Embodiment 1, the lower mold 210 has a horizontal mold core 230 below each vertical mold core 220. The horizontal mold core 230 is positioned according to the horizontal state of the square tube, meaning its vertical dimension is smaller than its horizontal dimension. Furthermore, a slot 233 is reserved between the horizontal mold core 230 and the vertical mold core 220. The horizontal mold core 230 has a second mold hole (not shown in the drawing) corresponding to the first mold hole 224. Each horizontal mold core 230 has a second outer end face 231 facing the opposite horizontal mold core 230, and each second outer end face 231 has chamfered edges on all four sides to form a second guide slope 232. It is understood that the horizontal mold core 230 can also be positioned above the vertical mold core 220, and is not limited to the above embodiments.

[0051] Using the above structure, when punching holes in the wide face of a square tube, the wide face of multiple square tubes is first placed on the first conveyor line 300 as the bottom surface. The first conveyor line 300 conveys the multiple square tubes. At the same time, the first stop mechanism 600 drives the first stop part 610 to rise, thereby limiting the position of the multiple square tubes on the first conveyor line 300. After the first inductive switch 611 on the first stop part 610 is triggered for a period of time, the lifting mechanism 700 drives the lifting part 710 to lift the multiple square tubes upward. In this embodiment, the second inductive switch limits the lifting height of the lifting part 710, so that the square tubes can be aligned with the transverse mold core 230 in height. Following this, the two motion modules 200 move towards the first conveyor line 300 under the drive of their respective hydraulic cylinders until the transverse die cores 230 on both sides extend into the interior of each square tube. As the transverse die cores 230 on both sides gradually extend into the openings on both sides of the square tube, the two ends of each square tube can be positioned and supported outside the two vertical die cores 220 by the second guide inclined surface 232 and block the second die hole, thereby defining the relative position between the square tube and the lower die 210. Finally, the stamping mechanism 500 drives the upper die 510 to stamp towards the second die hole, thus completing the punching of the wide surface of the square tube.

[0052] After punching multiple square tubes, the upper die 510 is driven upwards by the stamping mechanism 500, and both motion modules 200 move away from the first conveyor line 300 under the drive of their respective cylinders, allowing the square tubes to fall back onto the first conveyor line 300. Since the first stop mechanism 600 has already driven its first stop part 610 to descend during stamping, once multiple square tubes have passed the first stop part 610, the first stop mechanism 600 drives its first stop part 610 to rise, and the multiple square tubes are unloaded under the conveying of the first conveyor line 300.

[0053] like Figure 6 and Figure 7 As shown, the profile processing line according to a second aspect embodiment of the present invention includes a punching assembly 10 according to the first aspect embodiment of the present invention, and further includes a feeding assembly (not shown in the drawings), a cutting assembly (not shown in the drawings), and a second conveyor line 20. The feeding assembly can feed multiple profiles, and the fed profiles are conveyed to the cutting assembly for cutting to obtain square tubes of a specified length. Since the feeding assembly and the cutting assembly are both prior art, their specific structures and working principles are not described in detail in this embodiment.

[0054] Multiple square tubes, after being cut, are conveyed to the second conveyor line 20 for transport. The second conveyor line 20 has a conveying direction from back to front, and the first conveyor line 300 is connected to the side of the second conveyor line 20. If punching is required for the square tubes, an openable baffle 21 is installed in the middle of the second conveyor line 20. The baffle 21 is driven by a cylinder, and a first pushing mechanism 22 is connected upstream of the baffle 21. The first pushing mechanism 22 is located on the other side of the second conveyor line 20. The first pushing mechanism 22 can be a cylinder and has a first push plate 23 that can extend and retract left and right. The first pushing mechanism 22 is used to push multiple square tubes from the second conveyor line 20 to the first conveyor line 300.

[0055] Based on the above structure, when it is necessary to punch holes in multiple square tubes on the second conveyor line 20, the steps are as follows:

[0056] 1. The baffle gate 21 closes the second conveyor line 20 under the drive of the cylinder, so that the multiple square tubes on the second conveyor line 20 all abut against the baffle gate 21;

[0057] 2. The first pushing mechanism 22 pushes multiple square tubes from the second conveyor line 20 to the first conveyor line 300, so that the multiple square tubes can be arranged laterally on the first conveyor line 300;

[0058] 3. The first baffle mechanism 600 maintains the upward movement of its first baffle part 610. After the first conveyor line 300 conveys multiple square tubes to the first baffle part 610, the multiple square tubes are arranged side by side in the left and right direction.

[0059] 4. Both motion modules 200 move along a direction close to the first conveyor line 300 under the drive of their respective hydraulic cylinders, and punch holes in the narrow or wide face of the square tube according to the aforementioned steps.

[0060] It should be noted that if punching of the square tube is not required, the baffle 21 is opened under the drive of the cylinder, and the square tube can be directly fed along the second conveyor line 20. Alternatively, a third conveyor line is connected to the side of the second conveyor line 20, and a baffle 24 is provided at the end of the second conveyor line 20. A second pushing mechanism 25 is connected upstream of the baffle 24. The structure of the second pushing mechanism 25 can refer to the structure of the first pushing mechanism 22. The second pushing mechanism 25 is used to push multiple square tubes from the second conveyor line 20 to the third conveyor line (not shown in the figure), so that multiple square tubes can be arranged laterally on the third conveyor line and fed under the conveying of the third conveyor line.

[0061] In some embodiments of this invention, both conveying lines 310 are connected to a second baffle mechanism. The structure of the second baffle mechanism can refer to the structure of the first baffle mechanism 600. The second baffle mechanism is located upstream of the first baffle mechanism 600 and has a second baffle part that can be raised and lowered. When the first pushing mechanism 22 pushes multiple square tubes that need to be punched from the second conveying line 20 to the first conveying line 300, the second baffle part can limit the orientation of the multiple square tubes, so that the multiple square tubes can be neatly arranged laterally on the first conveying line 300 to achieve preliminary alignment of the multiple square tubes.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
